Northwest Africa 8568 (NWA 8568)

(Northwest Africa)

Purchased: 2014

Classification: Iron meteorite (IVA)

History: Purchased in 2014 by Don Hurkot from Labenne, who acquired it in 2012 from a nomad in Algeria.

Physical characteristics: Single iron mass with oxidized exterior, centimeter-sized regmaglypts; specimen is 14 × 10 × 3.5 cm.

Petrography: (C. Agee, UNM) This iron meteorite consists primarily of kamacite with minor amounts of taenite. Taenite often occurs as isolated skeletal inclusions 5-50 μm wide, up to 1 mm long, within host kamacite. Etched surface on 60 mm × 30-20 mm slab shows kamacite bands with apparent width 0.3-0.5 mm. Neumann lines.

Geochemistry: Bulk composition, ICP-MS (C. Herd and G. Chen, UAb): Ni ? 5.1, Co 0.26 (all wt%); Ga 2.2, As 4.7, Mo 5.6, Ru 3.6, Pd 3.6, W 0.6, Ir 2.0, Au 1.8 (all ppm). EMPA, focused beam (C. Agee and N. Muttik, UNM): kamacite Fe 94.03±0.74, Ni 7.01±0.09, Co 0.45±0.08 (wt%), n=6; taenite Fe 75.86±6.37, Ni 23.60±6.09, Co 0.21±0.11 (wt%), n=3.

Classification: Bulk data by ICP-MS and structural classification are consistent with a IVA iron. Iron meteorite (IVA). Fine octahedrite.

Specimens: 21.6 g on deposit at UNM, KD Meteorites holds 306.6 g, Don Hurkot holds the main mass.
